Construction - Care Taken

Great care taken in construction process so that the structure is neat, attractive and follows plans accurately.

Construction was careful and accurate for the most part, but 1-2 details could have been refined for a more attractive product.

Construction accurately followed the plans, but 3-4 details could have been refined for a more attractive product.

Construction appears careless or haphazard. Many details need refinement for a strong or attractive product.
